To all whom; it may concern.-

Be it known that I, FREDERICK RICHARD SIMMs, a subject of the King of Great Britain, residing at Welbeck Works, Kimberley Road, \lVillesden Lane, Kilburn, London, England, have invented new anduseful Im rovements in Buffers for Use on Motor-vehic es, of which the following is a specification.

This invention relates to improvements in buffers for use on motor-vehicles, and has for its object to prevent damage to lamps, Wings, radiators, and other parts of the vehicle should the latter come into collision with an obstacle and also to guard against damage to persons or vehicles on the road.

According to my invention I provide a pair of bufiers, which are preferably of the pneumatic type and are attached to the front; side, or back of the frame of the ofsuitable brackets.

The buffers proper are preferably of a curved shape and may be constructed and applied 'in a manner similar to that used with pneumatic tires, or they may be made of solid rubber or of stuffed leather. 1

The bufi'ers may be, as above described, fitted in pairs to the front, and, if desired, to the back of the vehicle-frame, or single buffers extendingcompletely across the vehicleframe may be employed. e

The brackets may be arranged so as to slide longitudinally on the frame, and springs are provided to render them more elastic. Furthermore, any suitable mode of attaching the brackets to the vehicle-frame may be made use of, such mode being advantageously one which enables the buffer to be readily attached to any vehicle.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a motor-car fitted with a pair of buffers constructed according to my invention. Fig. 2 is a sectional side elevation of one of the buffers and -onnecting-brackets. Fig. 3 is a plan view of the same, showing the attachment to the vehicle-frame. Fig. 4 is'a view of" a detail hereinafter described. Fig. 5-is a plan view illustrating another method of connecting the buffer bracket to the vehicle-frame, and Figs. 6 to 13 are plan views illustrating modifications. I

a represents the frame of the vehicle, and b b the buffers, two of which are shown in Fig. 1

attached to the side of the vehicle-frame at the front thereof.

- In the construction illustrated in Figs. 1 to 4 vehicle by means pring d at its outer end is loosely held in the brazed or otherwise suitably secured to the outer side of the rim c. The clip is shown in end view in Fig. 4.

In Fig. 5 the spring-bracket d d instead of being rigidly secured directlyto the frame a is fitted in the brackets or clips f f which are bolted to the said frame a. In this construction the brackets have a certain amount of movement with respect to the frame.

In Fig. 6 I have illustrated a form of my invention wherein the buffer 1) is hinged at its inner end to the bar g, secured to the vehicleframe (1-, and is connected at its outer end to one end of the spring 11., the other end of which abuts against a stop h upon the bar 9.

Fig. 7 illustrates a form of my invention wherein the buffer 1) is centrally secured upon the outer end of a spiral spring 4,, the inner end of which is attached to a boss i, formed upon the front angle of the vehicle-frame a.

In the arrangement illustrated in Fig. 8 the buffer 1) is hingedat its inner end to the rigid framework It, whichis secured to the vehicleframe a in any suitable manner. The buffer is elastically held in the roper position b means of the flat spring which is fixed to the hinge at one end and at its other end issecured to the outer end of the buffer by means of a slidingjoint.

Figs. 9 and 10 show two forms of buffer which are similar in principle to that shown in Fig. 7, but wherein flat springs are used in lieu of the spiral spring shown in the previously-described construction. In Fig. 9 the spring m is attached to the inner end of the buffer, while in Fig. 10 the said spring m is attached at approximately the center thereof.

Fig. 1 1 illustratesa construction of the buffer wherein a combination of a flat-spring'and a spiral spring is made use of. The curved flat spring n is attached to the frame of the vehicle and to theouter end of the buffer b, the spiral spring 0 being introduced between the fiat spring 1 and the inner end of the buf- IIO ' fixed joint and the spring secured to the inner end of the bufier by a to "the outer end thereof by means of a siding joint, both springs being suitably attached to the vehiole-frame a.

In the modification illustrated in 13 the buffer 1) is secured to ,the outer end of a rigid tubular frame 1', which is adapted to slide in a socket s, fixed to the side of the vehicleframe a. The inner end of the tube 1' carries prising a yielding pad and a yielding sup-.

a piston which works within the socket s and bears upon a spiral spring 25, arranged between the said piston and the bottom of the socket s.

In all the above constructions it will be obvious that in addition to the elasticity provided by the bufler .b-itself there is also that by which the said buffer is attached to the vehicle-frame.

As above described I may employ a pair of buffers at the front of the vehicle, as illusthe vehicle.

trated, or a single buffer at the front thereof, or a bufier or buffers at the sides or back of Moreover, the buffer may be pneumatic, as illustrated, or of any other desired constructions'uch, for example, as of solid rubber or stufled leather.

By the use. of my improved bufiers the lamps, wings, radiators, front wheels, and other parts of .amotor-vehicle are protected g p V 914.171

against damage should the vehicle collide with an obstacle; also, the buffers serve to protect pedestrians or vehicles on the road and save wear of the vehicle itself, as also of the wheels and steering-gear thereof.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A device of the class described, comport for same adapted to be secured on the vehicle theopad and support being in sub-- stantially the same horizontal plane,.substantially as described.

2. A buffer for motorvehicles made in two sections each of said sections comprising a yielding pad and a yielding support for same adapted to be secured to the-vehicle, substantially as described.

3. A buffer for motor vehicles made in two sections, each of said sections comprising a yielding pad, a support for the same and a yielding connection between one end of said support and the vehicle, substantially as described.
